The Hills star Audrina Patridge was nice enough to have photos taken of herself in the buff a few years back - and those photos have arrived in the form of pictures online.

MTV's The Hills Audrina Patridge is a sexy brunette with a belly-button piercing who obviously isn't shy about her body and shouldn't be!

Patridge has appeared in seasons one, two and three of reality television show The Hills featuring Whitney Port, Heidi Montag and former Laguna Beach star Lauren Conrad.

22-year-old Patridge, who seems a little embarrassed by the leak, tells our pals at TMZ that she "took these photos years ago when I was just out of high school and beginning to model."

"I was young and very trusting of others and I didn't know to protect myself," she tells MTV.

"It is a lesson learned, for myself, and hopefully for the young girls who look up to me."
